As you know, I am using collections. To delete the duplicates, I must go to all photos and display the rejected.

I must use attributes. I have only master photos selected, yet three videos are shown that cause LR to crash as soon as these are seen. I want to deselect these, but LR crashes before I can get to them. If I try to delete other videos using attributes with videos selected, others that I have rejected are shown, but they will not be deleted.

Here is more data that may help you.
